I'm using a couple of cheap Kingston A400 for my setup (120 and 480 GB) and they work just fine. One thing I noticed is that the 120 GB one's health went down to 92%, from 100%, in "just" one year (smart parameter). But that's implies a lifetime of more that 12 years, so I'm not excessively concerned.
